Composite structure fluorescent ceramic with high efficiency and wide color rendering index for laser illumination and preparation method of composite structure fluorescent ceramic
The invention discloses high-efficiency and wide-color-rendering-index composite structure fluorescent ceramic for laser illumination and a preparation method of the high-efficiency and wide-color-rendering-index composite structure fluorescent ceramic. The fluorescent ceramic is of a three-layer composite structure sequentially comprising a (Re1-xCex) 3Al5O12 yellow-green fluorescent layer, a (A1-yCey) 3 (Al1-zBz) 5O12 red fluorescent layer and an AlN substrate layer from top to bottom. The preparation method comprises the following steps: respectively preparing a (Re1-xCex) 3Al5O12 single-layer ceramic biscuit, a (A1-yCey) 3 (Al1-zBz) 5O12 single-layer ceramic biscuit and an AlN single-layer ceramic biscuit through tape casting; sequentially laminating the three ceramic biscuits from top to bottom to form a composite structure casting sheet, and performing isostatic pressing to obtain a composite structure ceramic biscuit; and finally, sequentially carrying out glue discharging, high-temperature sintering and double-sided polishing to obtain the composite-structure fluorescent ceramic. The composite structure fluorescent ceramic obtained by the method can realize color tuning under reflection configuration, and has higher efficiency and color rendering index.
本发明公开了一种激光照明用高效率宽显指的复合结构荧光陶瓷及其制备方法，荧光陶瓷为从上往下依次为(Re1‑xCex)3Al5O12黄绿色荧光层、(A1‑yCey)3(Al1‑zBz)5O12红色荧光层、AlN衬底层的三层复合结构。制备方法：通过流延成型分别制备(Re1‑xCex)3Al5O12、(A1‑yCey)3(Al1‑zBz)5O12和AlN单层陶瓷素坯；将这三种陶瓷素坯依次按照从上往下的顺序叠层后形成复合结构流延片，再通过等静压成型得到复合结构陶瓷素坯；最后依次进行排胶、高温烧结、双面抛光即得复合结构荧光陶瓷。该方法所得到的复合结构荧光陶瓷可实现反射配置下的颜色调谐，具有更高的效率和显指。
